San Francisco 49ers DT Ian Williams (ankle) had offseason ankle surgery, and general manager Trent Baalke said Wednesday, April 20, that he did not have a timeline on when Williams would be ready to play. "Still underdetermined," Baalke said. "But he's making very good progress."

San Francisco 49ers DT Ian Williams (ankle) has undergone multiple surgeries on his ankle, and his status for Week 1 of the 2016 season is questionable at this point, according to sources. The two sides reached a one-year deal worth as much as $6 million after he failed his physical. Williams agreed to a five-year deal worth $27.5 million before the failed physical.

The San Francisco 49ers aren't expected to use the franchise tag this year, but if they do, DT Ian Williams would be a candidate. He's coming off his best year as a professional and stayed healthy for all 16 games after playing in 15 games combined in his first four seasons.
